The Demonstration Programs in Reading and Mathematics were initiated in California in an effort to improve the reading and mathematics performance of secondary school students from neighborhoods characterized by high poverty levels, transiency, and low test scores. The programs have operated in California schools for the past 11 years. Each program is evaluated annually using a formula that takes into account both student achievement and cost effectiveness. The report describes Demonstration Programs now being implemented in 21 California junior high schools: 12 reading programs, one reading and mathematics program, and eight mathematics programs. Each report includes a program profile and a general description of program offerings and operation. Some reports include descriptions of methods and materials used, the staff, physical space and hardware, and notes on replicating the program. (MK)
